35  * Represents an HTTP header field.
36  *
37  * <p>The HTTP header fields follow the same generic format as
38  * that given in Section 3.1 of RFC 822. Each header field consists
39  * of a name followed by a colon (":") and the field value. Field names
40  * are case-insensitive. The field value MAY be preceded by any amount
41  * of LWS, though a single SP is preferred.
42  *
43  *<pre>
44  *     message-header = field-name ":" [ field-value ]
45  *     field-name     = token
46  *     field-value    = *( field-content | LWS )
47  *     field-content  = &lt;the OCTETs making up the field-value
48  *                      and consisting of either *TEXT or combinations
49  *                      of token, separators, and quoted-string&gt;
